Baring 371 



Not closely allied to any other described species, being twice as 

 large as nigrina and stouter, with much larger, more coarsely and 

 somewhat less densely punctate prothorax. The punctures of the 

 inner intervals are finer than those of the others, as is frequently 

 the case. 



The following four species are more or less close relatives of 

 angusta Lee, differing from those of the nigrina section in the 

 generally more slender outline, absence of the longer white squam- 

 ules of the elytra and obsolete or feeble condensation at the base 

 of the third interval ; also in the finer and more widely separated 

 punctures of the interstitial series. By longitudinally reflected 

 light there is generally a more or less evident imbricate sculpture 

 visible on the lateral intervals. The very much larger discreta, 

 from Texas, is also to be placed in this angusta section, although 

 much less slender than the others and with coarser pronotal and 

 larger, though shallow, interstitial punctures, and with somewhat 

 coarser grooves : 



Pseudobaris tradita n. sp. — Elongate-oval, convex, rather shining and 

 deep black throughout; beak in the male rather slender, evenly arcuate, 

 subopaque and somewhat closely punctulate, fully as long as the head 

 and prothorax, the latter barely a fourth wider than long, the sides con- 

 verging and nearly straight to about apical third, there rounding rather 

 rapidly to the tubulate apex, which is just visibly more than half as 

 wide as the base, the basal lobe short, gradual and broadly rounded; 

 punctures relatively coarse and dense throughout though not in contact 

 or confluent, the median impunctate line wholly wanting; scutellum 

 small, transversely suboval; elytra elongate and obtusely subovoidal, 

 nearly one-half longer than wide, a Uttle wider than the prothorax and 

 twice as long, the humeral callus rather prominent, the grooves deep, 

 moderately coarse; intervals a little less than twice as wide as the grooves, 

 with feeble, well separated, transversely sublineate punctures; setae 

 indistinct, the basal condensations small but evident; abdomen with 

 small but deep, close but separated punctures, becoming coarser, longi- 

 tudinal and subrugose at the sides, the medio-basal impression of the 

 male rather long and narrow though shallow. Length (cf) 2.8 mm.; 

 width 1. 12 mm. Missouri, — Schuster. 



Stouter than angusta, with less cylindric prothorax, the sides of 

 which are more rapidly rounded and more anteriorly; also with 

 distinctly coarser pronotal punctures. I have associated with the 

 male type a female from Keokuk, Iowa, which resembles it very 

 closely but is much smaller in size.
